Be known that I, TERRENCE P. MAHON, or the city and county ofPhiladelphin and State of Pennsylvania, have invented an In]- lug refuse matter, and consists'of certain int provernents which are fully set forth in the 7 following specification, and are shown in the odors is prevented.

accompanying drawings. 7

My improved furnace is designed forburulog all manner of refuse matter, such as garbage-,iewage, &c., so theta. practically coon and the escape of noxious vapors and foul Such an apparatus may be employed in large cities for the destruction of waste matter, without the dissemination of foul odors and unwholesome gases My invention relates to certain improve ments in the construction of the furnace for the purpose of producing a. more complete -cor nb'nstion of the refuse matter and of preventing the escape of noxious odors and vapors into the atmosphere.

Another featureof my invention relates to the employment of condensing devices with thedraft flue, or fines, whereby animal or vegetable oils held in suspension in the vnpors or gases may be reclaimed.

Myinvention also relates to various iniprovements in construction and to novel coinbinations of. parts which are hereinafter fully described and claimed. 7

I shall now refer to the'acc'oin enying drawingsior the purpose of. explaining my inven-' tion. I v

I shall now describe the operation of my incinerating furnace. Fire is built upon the grate G2 which receives its draft from the inletsj, j in. the rear of the furnace through the fiues'J, J. The products of combustion from the grate G pass through the flue G into the incinerati'ng chamber B and thence through the dues H'- into the second chamber H. In this second chamber H, a second fire is built upon the grate h which receives its draft through the fluesQ, Q. Theproducts of combustion from the chamber B combine with those from the chamber H and are thoroughly consumed. The garbage or refuse matter to be consumed is emptied into the hopperD through one of" the doors Bland when the trap or door I) and the damper l are opened it drops through the passage or pipe D into the incinerating chamber B where it is subjected to the heat from the fire on the grate G and becomes consumed. The. smoke and unburned particles of matter which pass oil" from the chamber B enter the second chamber H where'they are directly subjected to the fire upon the grate'hand are fully consumed so that substantially no unconsumed parti cles of garbage and refuse matter with the resultingefoul odor escape from the stack I into the atmosphere. When the damperl and door D are opened to permit the refuse \Vhen the door R is to be opened this flue T maybe opened to iuice IIO

the chamber B through the fine 1) into the tenk Dane. tb'us partially consome the refuse matter in the tank even beforeit passes into tbe chamber 13. The resell: oftbis operation "is that the passage fine D'will notbeoome clogged by large pieces of refuse lodging in The beet flames from the chamber once where complete comi astion is plisbeii, This combnetiou of the inn-consumed perticlen of refuse matter may be fnrtiier in creased by opening the damper lend leading ilieproriuets of combustion from the chamber B, or part of thcnntbrough the flues Q2170 the. ash pit ofthe chamber H, sotbatthey will pass (iirectly through the burning fuel'on the grate in As the draft which supplies the fuel on the grate G3, is conveyed by the fiues' J, J which lead from tlieliopper D, the noxious vapors, gases'and odors present in tbevhoppcr, Dare drawn with-the draft, and fed totlie f re on the grate G so tbattoey become com' pietely. destroyed. The esca e of these noxious va pore and micro into the air is time prevented.
